A. A gopher snake occupies a burrow made by the desert rat.
B. A chipmunk takes shelter in an oak tree and is protected from predators and in return, disperses seeds around the area.
C. Wasps lay eggs in the case of eggs laid by the praying mantis. When the wasp eggs hatch, the larvae feeds on the eggs of the praying mantis.
D. A tapeworm gets into a moose and causes harm

Answer: The genetic material must be a DNA double helix.
Explanation:
Genetic material is the material which resides in the nucleus or any other organelles within the cell which is responsible for development of traits in an organism. It is a hereditary material which passes from parents to their offsprings. It is not necessary the genetic material must be stored in the form of double stranded DNA instead it can be stored in the form of RNA which is single stranded genetic material it directly encodes for proteins during translation.
Answer:
D: Some traits in certain embryos disappear as the embryo develops.
Explanation:
Please tell me if I'm wrong
To give a direct answer, I’d have to know what gene we were looking at. However, in a general sense, when a genotype has two capital letters, it means that it’s homozygous dominant. Take for example:
R= tall stalk
r= short stalk
The uppercase R is a dominant allele, which means if the plant has the gene with this in it (RR or Rr) then it will have that trait. If it has two lowercase letters (rr) then it will be the recessive trait.
Using this example, RR would be the tall stalk. For whatever your question is, the dominant phenotype would be the answer.
